Perhaps someone was trying to be too clever.
The error:
cxx: Error: /usr/lib/cmplrs/cxx/V6.5-021/include/cxx/deque, line 574: #468 a
template argument may not reference a local type
detected during:
instantiation of "std::deque<T, Allocator> &std::deque<T,
Allocator>::operator=(const std::deque<T, Allocator> &)

{

{
if (size() >= x.size())
erase(copy(x.begin(), x.end(), begin()), end());
- else
- copy(x.begin() + size(), x.end(),
- inserter(*this,copy(x.begin(),x.begin()+size(),begin())));

+ const_iterator mid = x.begin() + difference_type(size());
+ copy(x.begin(), mid, begin());

}
return *this;
}
which is exactly what GNU's gcc-3.1 does here.
